DRILLING-MACHINE FOR ARETESIAN AND OTHER WELLS.

SPECIFICATION forming part of Letters Patent No. 234,346, dated November 9, 1880.

Application filed April 17, 1880. (No model.)

To all whom it may concern:

Be it known that I, PATRICK SWEENEY, of Leadville, in the countyof Lake and State of Colorado, have invented new and useful Improvements in Drilling-Machines for Artesian and other Wells, of which the following is a specification.

The object of my invention is to provide certain improvements in drilling-machines which are simple in construction and operation and effective in use.

The invention consists of a drum for the drill-rope loosely mounted on a shaft and provided with a rising curved flange on each end and with two studs on one end, the studs enlb b at the ends of the drums A and U, and can ;be fastened at either drum by means of a pin. .0, which fits into sockets (Zd in the frame of the machine. with a cross-bar, Z, which engages with the gaging with across-bar on the shaft and the rising flanges sliding on adjustable projec tions of the frame, thus causing the drum to move forward and backward on the shaft, whereby it is alternately engaged with and disengaged from the cross-bar, thus raising the drill and then permitting the same to drop.

It further consists in a drum for the sandpump rope, which drum is likewise loosely mounted on the same shaft, and is also provided with studs, in which a cross-bar of the shaft catches, thus rotating the drum when desired.

In the accompanying drawings, Figure 1 is a side elevation of my drilling-machine, showing parts of the frame broken out. Fig. 2 is a plan view of the same. Fig. 3 is a side elevation, and Fi 4 a plan view, of the curved standard for holding the projection for regulating the height to which the drill-bit is to be raised.

Similar letters of reference indicate corresponding parts.

The druinAis loosely mounted on a shaft, B, which is rotated by some suitable motive device attaehed at 0, The drum A is provided with curved rising flanges D D, attached to the opposite ends of the drum, and with two studs, E E, attached to the outer end, F, of the drum. A slotted right-angled arm, G, or a similar device is held on the frame H by a set-screw, I, and a slotted plate, J, with the end plate, K, is held on a curved standard, L, provided with a number of apertures, M, by a set-screw, N.

The rope 0, from which the drill-bit P is suspended, passes over the pulley Q, is coiled around the drum A several times, and is then wound onto the drum B, in front of the drum A. The rope is held on the drum A by the hinged lever S, which is locked by a nut, T. Another drum, U, is also loosely mounted on the shaft B, and upon this drum the rope V, from which .the sand-pump W is suspended, is coiled after passing over a pulley, X. The drum U is provided with two hooked "studs, m m, on its outer end, which studs are adapted to engage with a cross-bar, Y, fastened to the shaft B, adjoining the outer end of the drum U.

A friction-ban d brake, a, fit into the grooves The shaft B is also provided studs E E 011 the end F of the drum A.

The operation is as follows: If the shaft B is rotated from left to right, the ends of the cross-bar Z will rest against the studs E E and will rotate the drum A in the same direction, as indicated by the arrow a and the rope O will be wound upon the drum as it moves in the direction of the arrow 1) and raises the drill P. As the rising flange D rests against the fixed arm G, the drum A is moved in the direction of the arrow 67? as it rotates, for the width of the flange is oontinuallyincreasing, and as the arm Gr cannot give, the drum must necessarily move in the above-named direction; but as the arm or cross-bar Z is rigidly fixed to the shaft B, it follows that as soon as the drum has moved a certain distance in the direction of the arrow (1 the arm Z will be disengaged from the studs E E, and as the drum is loosely mounted on the shaft the drill P will drop and will rot-ate the drum A in the inverse direction of the arrow a but if the drum Arotates in the inverse direction of the arrow a the rising flange D, which rises in the opposite direction of the rising flange D, slides along the head of, the slotted plate J and pushes the drum back in the inverse direction. of the arrow (1 so that the arm or cross-bar Z can engage with the studs E E, when the abovedesoribed movements are again repeated, thus causing a rising and falling of the drill P. The height to which the drill is to be raised before dropping can be regulated by means of the angle-arm G and the plate J, both of which can be adjusted to have greater or less pro jection, and thus push the drum a greater or less distance along the shaft B. If the drill is to be raised very high before dropping, the projection of the plate G need be but slight, and this projection must increase as the height decreases. The strokes can also be shortened by fastening the plate J nearer to the outer end,n, of the curved standard L. As the drill-hole increases in depth the rope is uncoiled from the drum R and locked on the drum A by the lever B, so as to leave the requisite length for drilling.

1f the sand is to be removed from the drillhole, the sand-pump W is lowered, its descent being controlled by the brake a. It the sandpump is to be raised, the drum U is moved in the direction ofthe arrow f until the crossarm Ycatches in the studs m m. As the shaft rotates from left to right the drum U will also be rotated in this direction. the rope V is wound onto the same, and the sandpump is raised. 1f the drill is to be lowered into the drill-hole, the brake a can also be applied on the drum A.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. In a drillii'igmachine, the drum A, constructed, substantially as herein shown and described, with the curved flanges D D rising in opposite directions on the two ends, as set forth.

2. In a drilling-machine, the combination, with the drum A, of the rising flange D and the arm G, substantially as herein shown and described, and for the purpose set forth.

3. Ina drillingmachine, the combination, with the drum A, of the rising flange D, the arm G, the studs E E, and the cross-bar Z, substantially as herein shown and described, and for the purpose set forth.

4. In a drilling-machine, the combination, with the drum A, of the rising flange D, and the plate J, and the standard L, substantially as herein shown and described, and for the purpose set forth.

5. In a drillingemachine, the combination, with the shaft B, of the drumsA and U, loosely mounted thereon and provided with projecting studs, and of the cross-bars Y and Z, substantially as herein shown and described, and for the purpose set forth.

6. The combination, with the rope O, of the drums A and It and the locking-lever S on the drum A, substantially as herein shown and described, and for the purpose set forth.

7. The combination, with the standard L, of the slotted guide-plate J, the set-screw N, and the apertures M M, substantially as herein shown and described, and for the purpose set forth.
